I just set-up a front pump on mine, though do have the auxiliary vale which was already in place. Dan   [Reply]   [No Email]

Several months ago someone posted some very good pictures of a 2 spool aux. valve. Yes it would run double acting cylinders but could also be adjusted for single acting. I have the same valve on my tractor. One lever supplies oil to the 3 pt. and the other is for aux. hyd's. They can't be used at the same time. Dave   [Reply]   [No Email]

Without the valve, when you lift the quadrant lever oil is pumped to the lift cylinder to raise the 3-pt. With the ISO valve fitted by holding one lever back oil is pumped to the couplings mounted on the rear of the tractor. The 3-pt is held in place and will stay up subject to the condition of the system. If you do not already have them you will need two hyd hoses to reach the rear, two quick release couplings and clamps to mount the couplings usually on two of the axle housing bolts. Fitting the valve is straight forward. When you lift the cap off, if you have Pressure Control (unlikely on a 35) the tube will lift a little. If not the tube may come out with the cap. It will be necessary to 'fish' around a little to engage the bottom of the tube in the pump port. With the tube in place make sure the O ring on the face is present and carefully fit the valve over it. You may need longer 7/16 unc bolts. Connect up the pipes and couplings. Job done.

If you have to hold one lever back then that will provide a constant flow to an implement that has its own valve block and controls. You will need a return line to be fitted back to the tractor. The best place is via an adaptor at the oil filler plug next to the gear lever. DavidP   [Reply]   [Send Email]

The first, I drilled and tapped the transmission housing for the return. Then for the next one, somebody suggested tapping the filler plug. Which I did. About a month later, a guru here told us about the return port already on the tractor. It's a 3/8" or 1/2" pipe plug with an Allen hex socket head, located on the top of the left side of the cover under the seat. I had those covers off probably 2 dozen times at that point, and never noticed it. Duhhh! A second point - If you need to control one or more double acting cylinders with that switch valve, you can feed the port on the right spool into a remote conventional control valve with one or more double acting spools. Both spools on the switch valve on the transmission are locked back to operate the remote. It's been my experience that the 3 point arms on the 35 should be in a lower position to give full output to the remote. As the arms come up, pump flow is decreased. My remote valves are mounted up to the right of the throttle and steering wheel, on loader frames. I did have a three spool valve mounted on the right fender at one time.   [Reply]   [No Email]

Hello Jack, Whilst the return point on the side of the cover may be used, (done it myself) it is not the best place for the return line. Depending on the circumstances of the valve, pipework and implement being operated it may not be big enough. If you are operating a single acting ram such as a trailer the problem will occur when you want to let the body down. Oil from the pump is sent around the circuit and back to this return point. In order for the trailer to drop the oil in the cylinder also has to come down this line. So, in effect you have two lots of oil trying to pass through a hose which is probably 3/8" bore. Even if the hose is 1/2" it still has to go through the 'restrictor' which will be the fitting in the cover. The return line MUST be larger than the supply and all fittings kept as large as possible.
